Myinvention vhas reference to coinV operated vendinginachines, and relates more specially to certain` improvements `and attachments toa inachineuof` that type whiehis set `forthwin an application filed hy myself fin the Patent Ofliceof the United States on the twenty-ninth day'ofl July, '1929, Serial cNo.

381,744. The purpose ofthe present invention istoiprovidemeans wherehyany attempts to operate saidfinachine bythe use of, slugs` or other suhstitutesffor the `coin intended to be used in connectiontherewith willihe interferedwith rand defeated'.` y u @It is afcommon practice to 4undertakethe operation of coin controlled -machines and `the surreptitious removal ofy the `contents thereofhy the use ofworthlessmetal checks of a suitahle'size andfshapeto cause the openV ation of the machine. Some fof these are `formed of a metalwhich will respondto magl y netic influence,`while others" areof non-'magnetic, metal, land of special forms. One of `thesefof type quite largely used Vis in thel form ofa brass .disk of the size of a coin o f established` size for .operating a machine, with an opening in Vits center. In the present invention ineans is provided for interrupting the movement of a coin or check ofany kind that is introduced into themachine, at a`y point between the receiving slot andthe'coinhandling devices, and interfering with its furtherprQgreSs ifit is spurious. '-Inthe case of slugs orotherdevices which` arethus arrested means of a magnetic characteris provided for distracting such slug and diverting it from the 'regular course, for ejectionv from the machine. In the case of the ldisks with a central. opening,.a meansV is provided for detaining the same during the initial operation of the coin handling devices, so that the same will he held fromoperation therewith, and also `discharged from the 'machine without effecting the release :of anyof the contents thereof.` n y i 'i The particular construction, arrangement, and operatiomof thevarious parts of the in- Y vention will he more fullyunderstood from the following specification, taken inconnec# tion with the accompanying drawings, in

rss The `reference numherlY indicates acasing,y in `which is iixed a `front plate 2. Within the machine is a frame 3, above which is supported a parcel magazine] 4, just. beneath whichris a parcel discharge, frame5.`Roek` ingly supported at its. rear end is` a` shaft 6, the front end of which extendsthrough an opening inthe plate 2, and "is" provided fwith a thumb-turn 7. Fixed "to said shaft just in rear' ofthe plate 2 is a disk @containing a kcoin-'way 9, ,in `line with `aWcoin-slot lO ina plate 11` of the casing 1`.` Ontheedge ofthe disk 8 is a tooth 12, forengag'nient hyfa fpawl 13, to hold thedisk from rotation in the directionindicatedb' thearrQw in Fig. 3. Said tooth is'normal y spacedfr-om said pawl `a Alittle distance, as shown insaid Eig. ,3, per! f present invention.

"In rear ofthe diskS is circular plate 15,1. 0

Ation by side rods lfdpassing through perfo-` `,rated ears 17 ,on the sides ofthe.l plate` 15.` i Said plate is heldyieldinglyin contact with the disk Shy acoilediV spring .18 on the shaft` 6. On the inner-faceof the disk Sis fixed apair of spiral cams 19, operatinginfarcshaped channels 20 in the plate 15, and pivoted tothefupper edge` of the plate 15 is a er devices 22, operable in the discharge frame 5, to cause a successive removal of parcels contained in the magazine 4. The mechanism hereinbefore described is substantially the same as that set forth in said application now on tile.

On the inside of the plate 2, just beneath the plate 11, is a chute 25, forming a passage for a coin between the slot 1() and coin pocket in the disk 8. Secured in arecess in the inner face of the plate 2 is a spring-plate 26, the upper end of which bent into a stop 27, just beneath the chute Said stop is held normally in position to intercept a coin or other article passing into the chute, and is removed therefrom by the forward movement of the plate 26, into the position shown in F ig 2. This is accomplished by means of a pin 28 on the inner face of the plate 2G, engaged by a cam 29 on the outer face of the disk 8. Upon the thumb-turn 7 being operated in a clock-wise direction, the disk 8 is moved in the same direction, causing the cam 29 to force the pin 28 and'plate 28 outwardly and clearing the passage in the chute. In case a coin of recognized value is being held in the chute it immediately drops downwardly into the coin-pocket 9, and upon Ya continued rotation of the disk 8, raises the pawl 13, permitting a continued rotation of the disk, and resulting in the discharge of the coin into the lower part of the casing.

At one end of the chute is supported a small magnet 30,'which attracts a slug or spurious coin containing iron or similar metals, and draws them in the direction of the magnet, the chute being open at that end, and the magnet not being of suiiicient strength to support the object, it drops downwardly into a chute already provided in the machine, shown at 31, by means of which it is ejected from the machine.

To the rear wall of the chute 25 is attached a pair of ears 32, 'between which is' pivoted an arm 33, to the upper end or which is connected a pm 34, adapted for insertion into the passageway of the chute through an opening in said rear wall thereof. The pin is held normally in withdrawn position, as shown in Fig. 1, by means of a coiled spring on said pin, bearing against the head of the pin in one direction and against the wall of the chute in the other direction. The arm 33 is projected upwardly into a cam-end 36, and

the lower end of said arm carries a tooth 37,

for engagement with a lug 38 supported on a plate spring 39, fixed at one end to a bracket on the plate 15. As the disk 8 is turned the plate 15 moves inwardly, rocking the arm 33, and causing the pin 34 to enter the central opening of a perforated disk, such as is shown at 41, if such a disk is contained in the chute 25. If a more solid object is contained in said chute the spring support of the lug 38 permits it to slide beneath the tooth on the end of the arm 33, without rocking the same.

Vhen the upper end of the arm 33 is moved forwardly the cam-end 36 slides beneath a catch 42 pivoted beneath ears 43 fixed to the upper part of the chute 25, until the end of said arm is finally engaged by said catch, as shown in Fig. 2. This occurs during the initial rotation of the disk 8, and as said disk continues to rotate the plate 15 is carried farther to the rear, the lug 38 passing beneath the end of the arm 33, as before mentioned, and at approximately the same time the catch 42 is released by means of a wire arm 44 attached thereto, and having a downwardly bent arm in engagement with an abutment 45 on the plate 15. The continued inward movement of said plate forces said arm rearwardly, raising the catch 42, and per- Vmitting the spring 35 to return the pin 34 and arm 33 to their former positions. If one of the disks 41 has been detained by the pin 34 the withdrawal of the pin permits it to drop, but by this time t-he disk 8 has been moved so far that the disk 41 cannot enter same, but is either carried round the edge of the disk 8 into the chute 31, or falls into the large end of the coin-way 9, from which it is dumped into the chute 31 upon the return of the disk 8 to its former position. By means of a weight 46 on the downwardly bentportion of the Wire arm 44 said arm and the catch 42 are at all times retained operative positions.

There is a possibility of a coin which is released from the chute 25 being thrown to the side, of the coin pocket by a too rapid movement of the disk 8, and to prevent such a mishap the edges of the cams 19 are provided with enlargements 47, as shown in Fig. 5, which retard the initial movement of the disk.
